9.1.1 Restoring NSX Manager Backups
VMware recommends restoring a backup on a newly deployed NSX Manager appliance:
Restoring to an existing NSX Manager installation might also work, but is not officially supported or tested in-house. Internal testing is done with the assumption that the existing NSX Manager has failed, requiring that a new NSX Manager appliance be deployed.
The newly deployed NSX Manager appliance VM on which the restore is performed must be the same version as the NSX Manager appliance from which the backup was taken.
To restore an available backup, the Host IP Address, Username, Password, Backup Directory, Filename Prefix, and Passphrase fields in the Backup Location screen must have values that identify the location of the backup to be restored.
Note Take screenshots of the old NSX Manager appliance settings screen or note them so that they can be used to specify IP information and backup location information on a freshly deployed NSX Manager appliance.
